I first became aware of the SA4QE in about 2005 from an article in The Guardian. At that time I was mainly housebound with chronic illness, and knew no one else who participated, so I did the event solitarily for several years, leaving sheets of (I have to admit non-yellow) paper around the local village green next to the river. Leaving Hoban’s quotes here felt playful and subversive, a fitting tribute to a quixotic writer.
